Oh oh, Time is one thing but you have to play the cartridge as the changing magnetic field will settle the ferro fluid Takes an album or two to settle things down.

when i placed he fluid i shook the bottle and drew up when it was mixed but he drops that came out of he syringe looked too clear.The turntable has a repeat feature so that when I sat down to listen a record had already been playing for an hour on repeat.
now after a few more records last night details are more present but didn't jump out or no WOW moment kind of thing. was I supposed to get more? Or does it sound like I didn't place the fluid correctly?
the cartridge is far beyond it's original sound. Much smoother, detailed, clear, and open.

My ferrofluid looks dark almost black.
I use a toothpick, mainly cause I have trouble controlling the diabetic syringe. When placing the ferrofluid you can see it wick almost instantly into the coils, Be sure that you pace about the same amount in the top and bottom coils. That is difficult because the magnetic field causes the fluid to sort of "jump" right out and usually not to where you really want it. The bottom coils are especially hard to access. Normally i can see a bit of the ferrofluid lingering for a second or two before it wicks away.
The idea here is the ferrofluid is filling the gaps in the coil windings in order to present a more "solid" magnetic field. If you think you placed a bit too much and the ferro fluid has a consistent presence on the coil windings, I use a common q-tip pressed gently against the coil in question to wick away a bit of the fluid. Be very careful as those damn coil wires are tiny and easily torn.
Incidentally you should get the Mu metal any day now. Three pieces, two for the sides and one under the front magnet. They are very tiny of course....
Incidentally I also impregnate the motor coil windings of my CD player (focus motors) Been using primarily on Sony transports with no issues.
It does add dynamics and detail as the focus motor simply reacts faster to the servo systems. Have to be careful to add equal amounts to the four coils, though or the servo system will react assymetrically
unfortunately i killed the black and the left channel on the GTE trying to place the ferro fluid. taking a little break.
just when the going was getting good.....
my condolences and I really can sympathize. all the pics i showed were of dead bodies....
i cancelled the 8MZ stylus in exchange for a vivid stylus for the Shure M97x. See if i can't kill that next.
I did place two circular cutout magnets on the front of a DL-103 and it reduced noise a bit. also on front of an Audio Technica AT14sa - but didn't notice anything.
I shoulda left that Black alone when I had it where it was. Just wanted to add more ferro.
Question: when placing the magnets on cartridges is it best to align straight at the magnet? Or lower towards the coils?
Idea is to concentrate the magnetic field on the coils, Makes for a more powerful motor assembly. You want to work with the existng magnetic field just strengthen it.
Most MC type have a yoe type assembly:magnet (s) on top and two pole pieces extending down ( like a horseshoe) to focus the field on the coil structure. Some MC use dual magnets front and rear instead
Of course MM are different, although the Grado follows the MC type construction. Shures literally have a moving magnet in the stylus assembly and the coils are on u shaped former going vertical and then back down.
so moving the magnets down toward the stylus on the 103 gets them closer to the coils.
I will have to have a look at the Shure's stylus when I get it. I may buy one of those $20 Shure's stylus' just to mess with.
